Primo ARM Miner Android app dashboard mining Verus at 5.91 MH/s with 8 thread chips, 37 accepted shares

Built for ARM. Not ported to it.

What one binary does on every ARMv8 device.

Pure ARM-native

No SSE-to-NEON translation layer; hot paths are ARM intrinsics and hand-tuned AArch64 assembly using PMULL, AES and SHA2 hardware crypto.

Four algorithms

VerusHash 2.2 (Verus), RandomX (Monero), scrypt (Litecoin + Dogecoin merged), SHA256d (Bitcoin).

Per-core runtime optimization

Detects big.LITTLE topology at startup and picks the fastest kernel per core; one binary is optimal on every device.

Hotplug-resilient core pinning

Pins reconcile continuously; the miner re-adopts cores Android parks and wakes instead of losing them.

Self-verifying

Every optimized kernel (including the assembly) is cross-checked against a reference implementation at startup; the miner refuses to run on mismatch.

Full stratum

Multi-pool failover, TLS (stratum+ssl://), Verus/standard/Monero dialects, ccminer-compatible CLI, config format, and monitoring API.

Tiny footprint

Single ~508 KB binary, two runtime libraries (libcurl, libjansson).

Android APK

The same native miner in a one-tap app: per-algo profiles, pool failover, live dashboard, in-app log viewer.

Measured, not projected.

Measured on RK3588 (4×Cortex-A55 + 4×Cortex-A76). Real hashrate depends on cooling, governor, and SoC.

Algorithm	A76 single core	8 threads
VERUSVerusHash 2.2	~1.44 MH/s	~7.5 MH/s
RANDOMXMonero	~160 H/s	~690 H/s
SCRYPTN=1024, LTC+DOGE	~4.8 kH/s	~25.9 kH/s
SHA256DBitcoin	~16.3 MH/s	~90 MH/s

Galaxy S10+ (Exynos 9820): ~5.5–5.9 MH/s Verus, ~700 H/s RandomX across 8 threads.
RandomX fast mode needs ~2.5 GiB free RAM (automatic light-mode fallback on low-RAM devices) and runs hotter than the other algorithms.

The app, as it runs.

Real captures from a Galaxy S10+ — no mockups.

Dashboard mining Verus: 5.91 MH/s, 8 thread chips, 37 accepted, 0 rejected, live temperature — Mining Verus — 5.91 MH/s, thread chips, shares, temp.

Dashboard mining Monero RandomX: 760 H/s on moneroocean, 8 thread chips in Monero orange, share accepted — Mining Monero (RandomX) — 760 H/s, Monero-orange accent.

Dashboard mining scrypt on litecoinpool: 20.17 kH/s, 8 thread chips, live temperature — Mining scrypt (LTC+DOGE) — 20.17 kH/s on litecoinpool.

Dashboard mining SHA256d: 76.32 MH/s, 8 thread chips in Bitcoin orange, 2 accepted shares — Mining SHA256d — 76.32 MH/s via ARMv8 hardware crypto.

Termux session mining Verus: startup banner, CPU topology, dev fee line, thread pinning, accepted shares in green — Same binary in Termux — topology detection, pinning, accepted shares.

App configuration: algorithm dropdown set to verus, thread count, primary pool URL and wallet fields — Config — pick an algorithm, paste pool + wallet, done.

App configuration: pool list with failover explainer, network monitoring toggle and save button — Up to 3 failover pools; optional LAN monitoring API.

In-app log viewer showing accepted shares and per-thread hashrate lines — In-app log viewer — the full miner console, on the phone.

GPL-3.0-or-later

Nothing hidden.

A miner you can't audit is a miner you shouldn't run.

Dev fee, disclosed

One 60-second slice of mining per cycle on the developer's pool:

Verus — 2% (60 s per 50 min)
RandomX / scrypt / SHA256d — 1% (60 s per 100 min)

If the dev pool is unreachable your mining is never interrupted — the slice is skipped. It's GPL: forks may remove it. The fee logs itself in the console.

Open source

GPL-3.0-or-later. Full provenance of every optimized kernel is documented in-repo (PROVENANCE.md, NOTICE). Build it yourself and compare.

Verified at startup

Self-tests gate mining at startup — every optimized kernel is checked against a reference implementation. The monitoring API is read-only.

Donations

Donations fund ARMv9 test hardware (SVE2 boards and phones) for the next generation of optimizations.
